England and Jamie Vardy and Gareth Bale's Wales will aim to cement their places in the Euro 2016 knockout phase on Monday.

England, watched by Prince William, take on Slovakia in Saint-Etienne while Wales play Russia in Toulouse with all four nations still in with a chance of reaching the next round.

A draw for England would send them through to the next round, but a victory would guarantee top spot and a last-16 game in Paris.

Coach Roy Hodgson rewarded Leicester's Premier League-winning striker Vardy for his goal against Wales and the scorer of the winner in that 2-1 victory, Daniel Sturridge, by lining them up against the Slovaks. Wayne Rooney was rested.

Hodgson's side lead Group B on four points with Chris Coleman's Welsh side and Slovakia one point further back.

Around 1,800 police were on patrol in Toulouse to head off any repeat of the violence in Marseille around Russia's opening match against England.

The fallout from the fighting, much blamed on a group of well-prepared Russian hooligans, saw UEFA formally warn Russia they will be disqualified if there is more stadium trouble.

Many cafe owners in the picturesque centre of Toulouse decided to shut their terraces for the day to avoid damage.

English fans, whose behaviour in France has also earned a severe reprimand from UEFA, were also under surveillance in the central city of Saint-Etienne.

Russia have looked unimpressive so far, despite pegging back England, and have only one point, but they remain in contention.

In Toulouse, Real Madrid star Bale will try to exploit an ageing Russian back line.

Bale has scored two of his country's three goals, both directly from free-kicks, and the 26-year-old insisted his team-mates remain in high spirits despite their last-gasp defeat to England.

"We have to forget about it. It's over. Our fate is in our own hands, and if you'd given us this at the start of the tournament we would have taken it," said Bale.

Russian coach Leonid Slutsky said his team will not try to man-mark Bale.

"It's hard to man-mark footballing superstars," added Slutsky.

Wales can book their place in the last 16 with a victory, but a draw could also be sufficient to see the tournament debutants advance.

Manager Chris Coleman echoed Bale's optimism and believes Wales can keep their fans dreaming for some time yet after reaching their first major tournament finals since the 1958 World Cup.

"Look where we are, we're in a fantastic position. We're at our first major tournament, we've got the chance to progress. Our players have done unbelievably well," he said.

Russia must beat Wales to avoid a third straight group stage exit at a major tournament.

UEFA's disciplinary committee on Monday fined Croatia 100,000 euros ($113,000) for flares thrown on the pitch by its fans that halted Friday's match against Czech Republic.

UEFA also ordered the Croatian federation, the HNS, not to sell tickets to fans "identified by the HNS and the Croatian authorities as hooligans." But the ticket sanction was deferred until the end of the tournament.

Meanwhile Adidas announced a deal worth more than 50 million euros ($56.5 million) a year to remain supplier of the German national team, in the face of competition from Nike.
